Hi John

From your gallery I guess your using the 17-85mm lens IS

If you look at the photozone link your notice the lens is not a good performer in the distortion department at the wide angle end.

http://www.photozone.de/canon-eos/17...report--review

To correct for this the you need to correct for the barrel distortion before applying any perspective correction because the camera was not level.

You can get software to do these complex corrections but will it be worth it in your case.

The distortion is much reduced at the 24mm setting compared to 17mm so I would suggest using 24mm instead of the 17mm end for building work.

If you really need wide angle for building work then I would suggest getting a lens that has much less distortion at 17mm.

Hi John, looking through your gallery, I agree with Rob in some respects. The lens distortion can be corrected in Photoshop or through specialist software like DxO. But another answer is to look at the view again and use the lens to deliberately exaggerate the view and perspective. Also as Rob says it is essential to have the camera level, vertical and the plane as parallel to the building face as possible. A tilt backwards or forwards and lines fly out or in. This is why a lot of architectural photographers use tilt/swing/shift lenses. I use a 24 mm for my buildings. It is the Nikkor 24 mm PC-E lens.
